* [svn-r5571] Purpose:Quincey Koziol2002-06-101-4/+5
| | | | | | | | | | | Bug Fix (#709)/Code improvement. Description: Allow chunks for chunked datasets to be cached when file is open for read-only access. Platforms tested: IRIX64 6.5 (modi4) w/parallel
* [svn-r5530] Purpose:Bill Wendling2002-06-041-1/+1
| | | | | | | | | | | | | | | Code Cleanup Description: Removed some compiler warnings. Solution: In a few cases, NULL was being returned when a FAIL was supposed to be returned instead. There were some header files which needed to be included in a few of the sources. A couple of if-then statements had assignments in the conditional part. The compiler warned that they should have extra "()"s around them. Made the code check the values instead. Platforms tested: Linux (parallel) Modi4 (parallel)
* [svn-r5471] Purpose:Quincey Koziol2002-05-291-25/+27
| | | | | | | | | | | | | | | | Code cleanup Description: Broke the FUNC_ENTER macro into several macros, with more specialized uses (which followup mail will describe). This was designed to move most/all of the checks which could be done at compile time to that point, instead of needlessly performing them (over & over :-) at run-time. This reduces the library's size (and thus staticly linked binaries) and has a minor speedup effect also. Platforms tested: IRIX64 6.5 (modi4) with parallel & FORTRAN enabled, and additional testing on FreeBSD and Solaris immediately after the checkin.
* [svn-r5467] Purpose:Quincey Koziol2002-05-281-11/+19
| | | | | | | | | | | | | | | | | | | | | | | | Code cleanup. Description: Took Robb's recent ideas for improving the FUNC_ENTER/FUNC_LEAVE macros equivalents in the SAF library and adapted them to our library. I added an additional macro which is equivalent to FUNC_ENTER: FUNC_ENTER_NOINIT - Has the API tracing code, etc. from FUNC_ENTER but none of the library or interface initialization code. This is to be used _only_ for static functions and those which explicitly cannot have the library or interface initialization code enabled (like the API termination routines, etc.). This allowed many more of the functions in the library [but not all yet :-(] to be wrapped with FUNC_ENTER[_NOINIT]/FUNC_LEAVE pairs. It also reduced the size of the library and executables (by cutting out a bunch of code which was never executed), I'll e-mail the exact results when I've finished editing it. Platforms tested: IRIX64 6.5 (modi4)
* [svn-r5434] Purpose:Quincey Koziol2002-05-171-26/+39
| | | | | | | | | | | | | Code improvement. Description: Propagated the "fill time" property into the parallel chunk allocation routine, allowing it to avoid writing fill values to each new chunk allocated. This improves the performance of chunked datasets in parallel I/O to be on par with contiguous datasets again (on modi4). Platforms tested: IRIX64 6.5 (modi4)
* [svn-r5429] Purpose:Quincey Koziol2002-05-171-65/+102
| | | | | | | | | | | | | | | | | | | | | Bug fix/Code improvement. Description: Currently, the chunk data allocation routine invoked to allocate space for the entire dataset is inefficient. It writes out each chunk in the dataset, whether it is already allocated or not. Additionally, this happens not only when it is created, but also anytime it is opened for writing, or the dataset is extended. Worse, there's too much parallel I/O syncronization, which slows things down even more. Solution: Only attempt to write out chunks that don't already exist. Additionally, share the I/O writing between all the nodes, instead of writing everything with process 0. Then, only block with MPI_Barrier if chunks were actually created. Platforms tested: IRIX64 6.5 (modi4)
* [svn-r5271] Purpose:Quincey Koziol2002-04-261-1/+5
| | | | | | | | | | | | | | | | Bug Fix. Description: When the fill value for a dataset is not set, the size is set to zero, causing problems with filling unused areas in previously defined chunks (i.e. when the dataset shrinks in size) Solution: Use the size of the elements in the dataset directly, instead of relying on the size of the fill value (which must be the same size). Platforms tested: FreeBSD 4.5 (sleipnir)
* [svn-r5259] Purpose:Quincey Koziol2002-04-251-180/+143
| | | | | | | | | | | | | | | | Code cleanup Description: Previously, the I/O pipeline (pline), external file list (efl) and fill- value (fill) structs were passed down the raw data function call chain, even into and/or through functions which didn't use them. Since all three of these pieces of information are available from the dataset creation property list, just pass the dataset creation property list down the function call chain and query for the information needed in a particular function. Platforms tested: FreeBSD 4.5 (sleipnir)
* [svn-r5230] Purpose:Quincey Koziol2002-04-231-57/+76
| | | | | | | | | | | | | | | | | Code cleanup Description: Clean up the H5B_iterate code to not have a single hard-wired iterator for each interface which uses a B-tree, instead accept a function pointer which determines the callback function. This allows additional iterator callbacks to be defined without requiring additional H5B functions to be created. In that spirit, remove the H5B_prune_by_extent call and convert the H5F_istore callback routine for it into a callback routine for H5B_iterate. Platforms tested: FreeBSD 4.5 (sleipnir)

| | | | | | | | | | | | | | | | | | | | | | Purpose: H5Dset_extent API function Description: 1 new public function: H5Dset_extent, that allows shrinking a dataset several private functions that free the previously allocated chunks H5F_istore_prune_by_extent, H5B_prune_by_extent : removes the chunks H5F_istore_initialize_by_extent : initializes them with the fill value H5S_select_fill is used to fill the selection in the memory buffer Platforms tested: Windows 2000 SUN( arabica) LINUX (eirene) IRIX64 (modi4)
* [svn-r5142] ./hdf5-devel/src/H5Fistore.cRobb Matzke2002-04-051-3/+3
| | | | | | | | | Minor h5ls bugfix for compound types with array members. (Similar changes shortly for 1.4 branch). 2002-04-02 10:22:55 Robb Matzke <matzke@arborea.spizella.com> * H5F_istore_read: Realigned a couple of comments.
* [svn-r5130] Purpose:Quincey Koziol2002-04-021-20/+16
| | | | | | | | | | | | | | | | | | | | | | Bug Fix & Feature Description: The selection offset was being ignored for optimized hyperslab selection I/O operations. Additionally, I've found that the restrictions on optimized selection I/O operations were too strict and found a way to allow more hyperslabs to use the optimized I/O routines. Solution: Incorporate the selection offset into the selection location when performing optimized I/O operations. Allow optimized I/O on any single hyperslab selection and also allow hyperslab operations on chunked datasets. Platforms tested: FreeBSD 4.5 (sleipnir)
* [svn-r5109] ./hdf5-devel/src/H5Fistore.cRobb Matzke2002-03-281-1/+1
| | | | | Merge of name component length limit bugfix from 1.4 branch. A couple of very minor typos fixed.
* [svn-r4948] Purpose:Quincey Koziol2002-02-131-1/+2
| | | | | | | | | | | | | Bug fix Description: When a block was preempted from the chunk cache, it is possible that one of the pointers in the algorithm is invalidated and would generate a core dump. Solution: Re-calculate the internal pointer and move the the preemption after the re-calc. Platforms tested: FreeBSD 4.5 (sleipnir)
* [svn-r4891] Purpose:Quincey Koziol2002-01-311-88/+92
| | | | | | | | | | | | | | | Code speedup Description: Chunking I/O routines are reading in an entire chunk when performing I/O on the chunk, even if the chunk will be too large to cache. Solution: If the chunk is too large to cache, uncompressed and has been allocated space in the file, or if we are using the MPI-I/O VFD, perform the I/O directly to the chunk, instead of reading the chunk into memory, updating it and immediately writing the entire chunk back out. Platforms tested: FreeBSD 4.5 (sleipnir) (using serial access) and IRIX64 6.5 (modi4) (using parallel access with MPI-I/O)
* [svn-r4656] Purpose:Quincey Koziol2001-11-271-2/+4
| | | | | | | | | Bug fix Description: Moved some executable code out of an assert() and check the results of the code with an assert(). Platforms tested: Solaris 2.6 (baldric)
* [svn-r4643] Purpose:Quincey Koziol2001-11-271-17/+25
| | | | | | | | | | | | | | | | | | | | | | Code cleanup Description: Windows is generating hundreds of warnings from some of the practices in the library. Mostly, they are because size_t is 32-bit and hsize_t is 64-bit on Windows and we were carelessly casting the larger values down to the smaller ones without checking for overflow. Also, some other small code cleanups,etc. Solution: Re-worked some algorithms to eliminate the casts and also added more overflow checking for assignments and function parameters which needed casts. Kent did most of the work, I just went over his changes and fit them into the the library code a bit better. Platforms tested: FreeBSD 4.4 (hawkwind)
* [svn-r4621] Purpose:Quincey Koziol2001-11-201-5/+9
| | | | | | | | Code cleanup Description: Get rid of IDs from internal function calls. Platforms tested: FreeBSD 4.4 (hawkwind)
* [svn-r4482] Purpose:Quincey Koziol2001-09-261-2/+2
| | | | | | | | | | | | | | | | | | | | | | Kludge Description: Since we're only about halfway through converting the internal use of property lists from the "old way" to the generic property lists, we turned off snapshots to avoid exposing lots of API changes to users, until the APIs settled down. Getting the snapshots rolling again seems to have become a priority, so some changes are going to have to be made now that were going to be postponed until we were completely finished with the conversion. This requires that the old API functions be able to deal with both the old and new property lists smoothly. Solution: Kludge together the property list code so that they can transparently handle dealing with both the old and new property lists Platforms tested: FreeBSD 4.4 (hawkwind)
* [svn-r4473] Purpose:Quincey Koziol2001-09-251-1/+1
| | | | | | | | | | | | | | | | | | | | | Code cleanup for better compatibility with C++ compilers Description: C++ compilers are choking on our C code, for various reasons: we used our UNUSED macro incorrectly when referring to pointer types we used various C++ keywords as variables, etc. we incremented enum's with the ++ operator. Solution: Changed variables, etc.to avoid C++ keywords (new, class, typename, typeid, template) Fixed usage of UNUSED macro from this: char UNUSED *c to this: char * UNUSED c Switched the enums from x++ to x=x+1 Platforms tested: FreeBSD 4.4 (hawkwind)
* [svn-r4355] Purpose:Quincey Koziol2001-08-141-51/+51
| | | | | | | | | | | | | | | | | | | | | | Code cleanup (sorta) Description: When the first versions of the HDF5 library were designed, I remembered vividly the difficulties of porting code from a 32-bit platform to a 16-bit platform and asked that people use intn & uintn instead of int & unsigned int, respectively. However, in hindsight, this was overkill and unnecessary since we weren't going to be porting the HDF5 library to 16-bit architectures. Currently, the extra uintn & intn typedefs are causing problems for users who'd like to include both the HDF5 and HDF4 header files in one source module (like Kent's h4toh5 library). Solution: Changed the uintn & intn's to unsigned and int's respectively. Platforms tested: FreeBSD 4.4 (hawkwind)
* [svn-r4324] Purpose:Quincey Koziol2001-08-101-18/+11
| | | | | | | | | | | | | | | | | | | | | | | | New Features! Description: Start migrating the internal use of property lists in the library from the older implementation to the new generic property lists. Currently, only the dataset transfer property lists are migrated to the new architecture, all the rest of the property list types are still using the older architecture. Also, the backward compatibility features are not implemented yet, so applications which use dataset transfer properties may need to make the following changes: H5Pcreate(H5P_DATASET_XFER) -> H5Pcreate_list(H5P_DATASET_XFER_NEW) and H5Pclose(<a dataset transfer property list>) -> H5Pclose_list(id) This still may have some bugs in it, especially with Fortran, but I should be wrapping up those later today. Platforms tested: FreeBSD 4.4 (hawkwind)
* [svn-r4181] Purpose:Quincey Koziol2001-07-101-14/+13
| | | | | | | | | Bug Fix, Code Cleanup, Code Optimization, etc. Description: Fold in the hyperslab speedups, clean up compile warnings and change a few things from using 'unsigned' or 'hsize_t' to use 'size_t' instead. Platforms tested: FreeBSD 4.3 (hawkwind), Solaris 2.7 (arabica), Irix64 6.5 (modi4)
* [svn-r4038] Purpose:Quincey Koziol2001-06-211-3/+3
| | | | | | | | | | | | | Code clean/bug fix Description: H5FL (free-list manager) code currently is taking an hsize_t as the size of a memory block to allocate. On many machines, the size of an hsize_t is greater than the size of a size_t, potentially leading to incorrect memory allocations in rare circumstances. Solution: Changed hsize_t parameters and variables to size_t. Platforms tested: FreeBSD 4.3 (hawkwind)
* [svn-r4022] Purpose:Bill Wendling2001-06-191-11/+11
| | | | | | | | | Code Cleanup Description: Changed POSIX function calls to the HD* way of doing things. Checked with checkposix and tested on Linux. Platforms tested: Linux
* [svn-r3781] Purpose:Bill Wendling2001-04-051-14/+14
| | | | | | | | | | | | | | | | | | Update Description: Changed #include <hdf_file.h> construct to #include "hdf_file.h" so that the GNU compiler can more easily pick up the dependencies which it places in the .depend and Dependencies files. Also regenerated the Dependencies to go along with this. Platforms tested: Linux
* [svn-r3252] Purpose:Quincey Koziol2001-01-091-681/+689
| | | | | | | | | | | | | Code cleanup. Description: Fixed _lots_ (I mean _tons_) of warnings spit out by the gcc with the extra warnings. Including a few show-stoppers for compression on IRIX machines. Solution: Changed lots of variables' types to more sensible and consistent types, more range-checking, more variable typecasts, etc. Platforms tested: FreeBSD 4.2 (hawkwind), IRIX64-64 (modi4)

| | | | | | | | | | Feature symmetry Description: A while ago I needed to get the 'type' of data being accessed during writes to the VFL driver, so I put in code to get the information down there. Albert asked for the same information during reads, so I've added that in. Tested: FreeBSD 4.1.1 (hawkwind)
* [svn-r2652] Purpose:Quincey Koziol2000-10-101-5/+8
| | | | | | | | | | | | | | | Maintainance & performance enhancements Description: Re-arranged header files to protect private symbols better. Changed optimized regular hyperslab I/O to compute the offsets more efficiently from previous method of using matrix operations. Added sequential I/O operations at a more abstract level (at the same level as H5F_arr_read/write), to support the optimized hyperslab I/O. Platforms tested: Solaris 2.6 (baldric) & FreeBSD 4.1.1 (hawkwind)

* [svn-r2057] Purpose:Albert Cheng2000-03-241-2/+2
| | | | | | | | | | | | | | Bug fix for parallel mode. Description: H5FD_mpio_tas_allsame was called for all cases, even when MPIO is not used for access. That corrupted the internal file handle structure. Solution: Define a macro, IS_H5FD_MPIO(f), for testing if f is opened with MPIO access. Will call H5FD_mpio_tas_allsame only if this condition is true. Platform tested: O2K, both -64 and -n32 modes.

* [svn-r1585] Changes since 19990820Robb Matzke1999-08-241-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- ./src/H5D.c Added additional elements to a variable initializer in H5Dvlen_get_buf_size() to shut up a warning message. Also added the API tracing call. ./src/H5F.c Added file opening optimizations. If the driver doesn't support the ability to determine when two file handles refer to the same file (like MPIO and GASS) then H5F_open() makes fewer calls to the driver's open callback. Also, if the tentative file access flags are the same as the original flags then H5F_open() makes fewer calls to the file device. ./src/H5FD.c ./src/H5FDprivate.h ./src/H5FDpublic.h Added H5FD_get_class() so the library can get information about what file driver callbacks are defined. This will be useful when more optimization functions are added to the VFL, such as for MPIO derived datatype I/O. ./src/H5FDcore.c ./src/H5FDfamily.c ./src/H5FDmpio.c ./src/H5FDmulti.c ./src/H5FDsec2.c The driver symbols (like H5FD_CORE, etc) are actually function calls. The functions were fixed to return correct values even after calling H5close(). ./src/H5FDmulti.c ./src/H5FDmulti.h Added support for opening a file when parts are missing (only if the caller explicitly allows that in the file access property list). Moved some common code sequences into macros or functions. Added better support for reopening files. All the application has to know is that the file is a multi file and the base name from which all the member names are created. More debugging output when the file is opened with the H5F_ACC_DEBUG flag. Fixed various bugs. ./src/H5Fistore.c Chunked raw data was accidently allocated as meta data instead of raw data. ./src/H5I.c The H5Iget_type() function fails when invoked with an old object ID (an ID which has been closed down). ./test/h5test.c Added an extra argument when setting the multi file access property lists so the test fails if it can't open one of the sub-files. ./tools/h5ls.c Improved the algorithm for deciding what file driver to use. It basically tries all of the predefined drivers and is now able to open family, split, and multi files without looking for special characters in the file name. Added `-e' and `--errors' switches which cause errors from libhdf5 to be reported on stderr in addition to the simple error message displayed by h5ls.
* [svn-r1574] Changes since 19990817Robb Matzke1999-08-181-2/+2
| | | | | | | | | | | | | | | | | | | | | ---------------------- ./src/H5D.c ./src/H5F.c ./src/H5FDmpio.c ./src/H5Fistore.c ./src/H5Fprivate.h ./src/H5Smpio.c The `driver_id' for a file was accidently put in two structs. I removed it from the H5F_file_t struct since it's really an attribute of the VFL stuff. More careful incrementing/decrementing the driver ID to fix a memory leak. ./src/H5P.c Rewrote H5Pcreate() in terms of H5P_copy() of a default property list. This fixes some referencing counting bugs.
* [svn-r1573] Changes since 19990817Robb Matzke1999-08-171-2/+2
| | | | | | | | | | | | | | | | | | | | | ---------------------- ./src/H5D.c ./src/H5F.c ./src/H5Fistore.c ./src/H5Smpio.c Incorporated previous changes into MPIO special cases. These are mostly due to the fact that most of the members of the file->shared->fapl struct have been moved into the file->shared->file->shared struct (`file' is an H5F_t*). ./src/H5I.c Fixed a bug with closing the library w.r.t. the VFL stuff. The VFL layer introduced reference counts on object ID's and the library termination functions freed these objects in the wrong order. Now H5I_clear_group() does not normally remove objects with a reference count larger than one because it assumes that those objects are currently in use by the library.

The H5Pset_fapl_split() function just calls H5Pset_fapl_multi() with arguments which prepare to split the address space into two files: meta and raw data. This is the first version. I plan to allow the open() call to relax a bit which would allow one to open an hdf5 file when only the meta-data file is present. This would allow a very large file to be split and stored on tape and the relatively small meta file to be mirrored on disk to allow limited browsing of the file (any request for raw data would fail). ./src/H5private.h ./src/H5F.c ./src/H5FD.c ./src/H5FDprivate.h ./src/H5FDpublic.h ./src/H5FDcore.c ./src/H5FDfamily.c ./src/H5FDmpio.c ./src/H5FDsec2.c Added the ability for a file driver to store information in the superblock which would be needed if the file were opened again later for reading. The format is driver-defined which allows users to extend it however they like. ./doc/html/H5.format.html Added information about the new driver information block of the superblock. This is where file drivers store information they need in order to reopen the file later. ./src/H5F.c ./src/H5Fprivate.h ./src/H5FD.c ./src/H5FDprivate.h ./src/H5FDpublic.h ./src/H5FDcore.c ./src/H5FDfamily.c ./src/H5FDmpio.c ./src/H5FDsec2.c ./src/H5Fistore.c ./src/H5R.c The file access properties and the file access property list were decoupled, which allows the property list to more cleanly contain properties for various levels of the file and which allows the property list to be modified more cleanly when opening files. ./src/H5.c ./src/H5FDpublic.h Removed H5FD_MEM_META and H5FD_MEM_GROUP since they're never used. ./src/H5D.c Changed the way we detect the MPIO driver in all these special cases. ./src/H5F.c ./src/H5Rpublic.h ./test/tfile.c The default file sizeof(offset) was changed to be a function of haddr_t instead of hsize_t. THE H5RPUBLIC.H DEFINITIONS WILL HAVE PROBLEMS IF THE USER CREATES A FILE WITH NON-DEFAULT OFFSET AND SIZE SIZES! ./src/H5F.c Fixed an uninitialized memory access bug in file closing related to the VFL. ./src/H5T.c ./src/H5Tpublic.h Added an H5T_NATIVE_HADDR predefined datatype which corresponds to the `haddr_t' type. ./test/Makefile.in Reformatted long lines. ./test/big.c ./test/cmpd_dset.c ./test/dsets.c ./test/dtypes.c ./test/extend.c ./test/external.c Removed the H5F_ACC_DEBUG flag from file creation/open calls. ./test/big.c Plugged a memory leak. ./test/h5test.c Added support for the `multi' driver. Removed #warning about not having the stdio driver. Plans are to not implement it since the sec2 driver serves the same purpose and testing didn't show any difference in execution times between the two.

I've ported and tested the sec2, family, and core drivers and only ported the mpio driver (Albert will test it). So if you need MPIO I would recommend sticking with the previous version for a while. You will get a few compile warnings about split and stdio drivers not being implemented and possibly tracing information not inserted in some of the drivers. You can safely ignore them but I plan to fix them. I'm still working on the split driver because I just realized that it needs a part of the VFL that isn't written yet. Documentation is being updated also because there were some minor changes (mostly just name changes). It should be available on my web site later this week. ./MANIFEST ./src/Makefile.in ./src/hdf5.h ./src/H5Flow.c [REMOVED] ./src/H5Fstdio.c [REMOVED] ./src/H5Fsec2.c [REMOVED] ./src/H5Fsplit.c [REMOVED] ./src/H5Fmpio.c [REMOVED] ./src/H5Ffamily.c [REMOVED] ./src/H5Fcore.c [REMOVED] ./src/H5MFpublic.h [REMOVED] ./src/H5FD.c [NEW] ./src/H5FDcore.c [NEW] ./src/H5FDcore.h [NEW] ./src/H5FDfamily.c [NEW] ./src/H5FDfamily.h [NEW] ./src/H5FDmpio.c [NEW] ./src/H5FDmpio.h [NEW] ./src/H5FDprivate.h [NEW] ./src/H5FDpublic.h [NEW] ./src/H5FDsec2.c [NEW] ./src/H5FDsec2.h [NEW] Removed/added files for virtual file layer. ./bin/trace ./src/H5.c Removed unused public datatypes and added new VFL public datatypes. Changed an error message. ./config/BlankForm ./config/dec-flags ./config/gnu-flags ./config/hpux10.20 ./config/hpux9.03 ./config/irix5.x ./config/irix6.x ./config/solaris2.x ./config/unicosmk Removed the H5F_OPT_SEEK and H5F_LOW_DFLT constants from the configuration since they're no longer applicable. The default file driver is always the sec2 driver and it always optimizes calls to lseek() or lseek64(). ./config/depend.in C preprocessor errors generated during automatic dependency building are sent to /dev/null to prevent them from appearing twice in the make output. ./src/H5AC.c ./src/H5B.c ./src/H5D.c ./src/H5F.c ./src/H5G.c ./src/H5Gent.c ./src/H5Gnode.c ./src/H5HG.c ./src/H5HL.c ./src/H5O.c ./src/H5Oattr.c ./src/H5Odtype.c ./src/H5Oefl.c ./src/H5Oshared.c ./src/H5T.c ./src/H5detect.c ./test/ohdr.c Changed H5F_ADDR_UNDEF to HADDR_UNDEF to be more consistent with the `haddr_t' datatype which is now a public type. ./src/H5D.c ./src/H5P.c ./src/H5Ppublic.h ./src/H5Tconv.c ./test/cmpd_dset.c ./test/dsets.c ./test/overhead.c ./test/tselect.c ./test/tvltypes.c The H5P_DATASET_XFER constant was changed to H5P_DATA_XFER because the properties apply to all types of I/O operations, not just datasets. ./src/H5B.c ./src/H5Bprivate.h ./src/H5D.c ./src/H5Dpublic.h ./src/H5F.c ./src/H5Farray.c ./src/H5Fistore.c ./src/H5Fprivate.h ./src/H5Fpublic.h ./src/H5Gnode.c ./src/H5Gpkg.h ./src/H5HG.c ./src/H5HL.c ./src/H5O.c ./src/H5R.c ./src/H5Sall.c ./src/H5Shyper.c ./src/H5Smpio.c ./src/H5Spoint.c ./src/H5Sprivate.h ./test/big.c ./test/h5test.c ./test/istore.c ./testpar/t_dset.c ./testpar/t_file.c ./tools/h5debug.c ./tools/h5ls.c Modified to work with the virtual file layer by calling H5FD_* functions instead of H5F_low_* functions and by passing file access and data transfer properties by object ID instead of pointer. Changed H5D_transfer_t to H5FD_mpio_xfer_t since the COLLECTIVE vs. INDEPENDENT transfer mode is specific to the MPIO file driver. Moved MPIO-specific stuff into the MPIO driver. ./src/H5B.c ./src/H5D.c ./src/H5Fprivate.h The H5F_mpio_* private functions were renamed and placed in the H5FDmpio driver except those which appeared in H5Smpio.c. ./src/H5E.c ./src/H5Epublic.h Added major error number H5E_VFL for virtual file layer related errors. ./src/H5F.c ./src/H5Fprivate.h Changed the logic that controls whether the boot block is written. Instead of assuming that the first call to write the boot block is only to allocate space, I've added a function argument which makes this explicit. Changed the way files are compared so that a driver-defined comparison function can be called. Files which belong to different drivers are always considered different. Removed H5F_driver_t since file drivers are now identified by object ID instead of a special non-user-extendible datatype. Removed all the hard-coded low-level file properties which have been replaced by the various file drivers. ./src/H5I.c ./src/H5Iprivate.h Added the H5I_inc_ref() which was removed a few months ago since we finally have a use for it. ./src/H5Ipublic.h Added the H5I_VFL object ID type to identify file drivers in the virtual file layer. ./src/H5MF.c ./src/H5MFprivate.h Moved all the allocation/deallocation code into the virtual file layer which allows file drivers to override much of it. ./src/H5P.c ./src/H5Ppublic.h Moved file driver-specific code into the various file driver files. The H5Pcopy() and H5Pclose() functions make calls into the virtual file driver to manage the memory for driver-specific file access and data transfer properties. ./src/H5private.h ./src/H5public.h The `haddr_t' type is now public. ./test/tfile.c Added a few more comments.
